Re: [postgis-users] how to get point, polygon value in postgis JDBC?

Hi all.
I have a big problem on my work.
First of all, the version based on my work is PostgreSQL : 8.1.11, PostGIS
: 1.5.2.
The problem is I can not get the value of Point and Polygon.
The code is below :
blah blah
--
-- public Test find(String Id) throws DAOException,
ClassNotFoundException, SQLException {
Class.forName(org.postgresql.Driver);
String url = jdbc:postgresql://localhost:8080/testdao;
Connection conn = DriverManager.getConnection(url, admin, apple);
PreparedStatement ps = conn.prepareStatement(select name, addr,
ST_AsText(position) from listFriend where id=?); ps.setString(1, Id);
ResultSet rs = ps.executeQuery();
//
((org.postgresql.PGConnection)conn).addDataType(point,Class.forName(org
.postgis.Point));
while(rs.next()) {
test = new Test();
p = new Point();
test.setName(rs.getString(1));
test.setAddr(rs.getString(2));
test.setPosition(p);
//System.out.println(rs.getString(3));
---
---
If I run the sentence, System.out.println(rs.getString(3));, it works. It
prints right output like Point(13.123 11.123).
But I don't know how to fix test.setPosition(p);
any helps will be thank.
P.S. is it possible to be reason why the low or high version of PostgreSQL
and PostGIS?
Best Regards
Kevin Lee.
Maybe you are looking for a WKT Parser? Like this one:
http://www.vividsolutions.com/jts/javadoc/com/vividsolutions/jts/io/WKTReader.html
If you are using the postGIS driver you should be able to use the geometry
directly on your query, instead of using as_text.

A stupid question, just in case. You say that AsBinary returns a valid
geometry, but does it have a collection with points? I mean, could it be an
empty collection?
Also, are you sure the encode function is not corrupted? If AsBinary returns
something hexadecimal, the encode function should have no problem, no matter
if the geometry is valid or not. Have you tried to run the encode function
with the result of the AsBinary? And with something simpler?

El Domingo 03 Julio 2011, James David Smith escribió: Dear all, I have a table of GPS points which are the locations of vehicles every 15 seconds. Each journey that a car makes has an ID. For example a taxi is on 'job 1' and has 50 points while it does this job, and then another 50 or 60 when it is on 'job 2' etc. What I would like to do however is investigate whether the car took the most effecient route between the two points. To this end I think that I can use the PGROUTING extension of PostGIS...? Does this sound possible? You can calculate the shortest path with pgRouting and then compare it with the length of the linestring formed with this GPS points. Probably you will have a longer path with the GPS points (because the GPS is never exact) but if you add a percent of error to the shortest path calculated by pgRouting you will know if the vehicle did a good or a bad path. I have found the PGROUTING website, and download the ZIP file for Windows installation, however I am not sure how to install it. Could somebody please tell me how or provide a link to a good place to read about how to install and use PGROUTING? Why are you using Windows (for any serious work)? There is a PPA for Ubuntu[1] which has a direct install while pgRouting binaries for Windows are old and strongly dependent of a postgresql version. And remember that you must install postgis first. Anyway, if you are thinking of having a real-time server with several vehicles sending positions every 15 seconds, forget Windows. It will be insane. If it is insane if you do it on a non-strongly-optimized database on Linux I don't want to know how hard it will be on Windows. Believe me, I have made a few of this real-time systems.

I don't want the users to be able to enable/disable the geospatialness of anyone else's columns. What's the right way to secure postgis so as to prevent this? It seems that a single, global, geometry_columns is the problem. I see a number of possibliities. If geometry_coulumns is all that needs to be secured I could create the table in each user's schema. If there's a lot of other infrastructure that needs to be duplicated this would not work as well -- the user's schemas would be all cluttered up. But I can see where having multiple geometry_columns tables could complicate an upgrade I could create a separate postgis schema for each user, but that seems overkill and I'm not at all clear on how $user is expanded in the search_path and whether or not it'd be possible to automatically have such schemas in the search path. then again I could just forget about it and hope the users don't kill each other. What's the best approach here? What if you write a trigger on every delete/update on the geometry_columns table? This trigger can cancel the delete/update if the user has no permission for that row. -- María Arias de Reyna Domínguez Área de Operaciones Emergya Consultoría Tfno: +34 954 51 75 77 / +34 607 43 74 27 Fax: +34 954 51 64 73 www.emergya.es ___ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users

You might need to add explicit type casts. I usually prefer to use ST_length instead of length. Maybe that's the problem?

[postgis-users] ShootingStar: Rule with comma separated... bug?
Hi, I'm trying to do a shooting_star calculation following this example: http://www.davidgis.fr/blog/index.php?2008/07/24/349-shooting-star-usage-example-with-turn-restriction But I think that it has a bug when reading the rule. If I try to set more than one restriction on a rule, like update routing set to_cost = 100,rule='9,5' where id = 6; it only works for the first edge defined on rule (9), not the second edge (5). Am I doing something wrong or is it a bug? If I invert the rule: update routing set to_cost = 100,rule='5,9' where id = 6; it works well for the first edge again (5), but not for the second (9). -- María Arias de Reyna Domínguez Área de Operaciones Emergya Consultoría Tfno: +34 954 51 75 77 / +34 607 43 74 27 Fax: +34 954 51 64 73 www.emergya.es ___ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users

If you need multiple restrictions for a given edge then you have to add multiple records for that edge each with a separate restriction http://pgrouting.postlbs.org/wiki/ShootingStar Fred.

Re: [postgis-users] lspostgis.sql shows errors
Now I understand, thanks. It was that, a configuration problem.

[postgis-users] lspostgis.sql shows errors
I'm trying to create a new postgis database on a postgresql 8.3. I have done it on the past on the same computer and it worked fine. But now, running lwpostgis.sql shows me errors: [...] psql:/usr/postgis-1.3.3/lwpostgis.sql:: ERROR: se ha denegado el permiso para crear �pg_catalog.geometry_dump� DETAIL: Las modificaciones al catalogo del sistema estan actualmente deshabilitadas. [...] After the first error, it rollsback the whole transaction. Could it be due to an upgrade of the library gdal? Or is it something easier? -- María Arias de Reyna Domínguez Emergya Consultoría ___ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users

Re: [postgis-users] buffer(the_geom, 0) crashes the database
El Martes 20 Enero 2009 12:13, Stefan Zweig escribió:
hi mark,
the file i have upload includes just a single query. it includes the
geometry (a multipolygon of russia) that crashes with buffer(the_geom, 0)
in wkt representation. so it is nothing more than select
buffer(geomfromtext('MULTIPOLYGON(.)',4326),0) i think without having
the actual coordinates of this MULTIPOLYGON it won't be possible to debug.
Then maybe it is a memory problem
